for fluids what is happening is that the original meshes are turned into a voxel (volumetric pixel) representation. The behavior of the voxels is calculated, then for each frame a mesh representation of the voxels is generated. So finding a way to correspond the verts of meshes between frames is non trivial.

could anyone post a node screenshot of how to setup vector blur? i can't get it to work.

I've coded the LBM algorithm myself - the velocity vectors of the boundary cells are part of the simulation and are calculated explicitly to perform the collide step. It would be nice if n_t could link this data to the vec data internal to the renderer.

Doubt it will happen soon...but it is a way.

The stucci texture doesn't appear to work...

Here u go

Theres something wrong with the alpha over node. Crashes every time.

Vector blur doesent seem to affect backround, is it in to-do -list?

Thanksos very muchos for the build and especially for the development. It truly rocks!

Problem with particles: Inside a nebula...
It looks render parts consider just the particles falling in it. This is the result:

while from far away...

thanks jarkkopoika!

koba,

excellent point. I'll email the suggestion to N_T.

Koba, LetterRip: I just looked at this a bit, shouldnt be too complicated - but the problem is more to get the fluid velocities into the blender speed calculation. I'm working on it

...

jarkkopoika: thanks for the DOF setup, thats quite cool - I was just wondering, how can you enable this render display in the image editor?

that DoF looks terrific!
